3 Claims.

This invention relates to new and useful improvements in folding chairs,and the primary object of the present invention is to provide a foldingchair that. is quickly and readily applied to seat boards in ball parks,circus tents and the like, whereby the back of the user will becomfortably supported.

Another important object of the present invention is to provide afolding chair including novel and improved means for hinging the seatsection to the back section, so that the same may be conveniently foldedwhen not in use.

A further object of the present invention is to provide a folding chairincluding a back, section so designed. as to give the maximum supportand rest to the back of the user.

A still further aim of the present invention is toprovidea folding chairthat is simple and practical in construction, strong and reliable inuse, neat and attractive in appearance, relatively inexpensive tomanufacture, and otherwise well adapted for the purposes for which thesame is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the present chair, and withdotted lines showing the clamping members in a folded position;

Figure 2 is a side elevational view thereof, showing the same applied toa seat board;

Figure 3 is an enlarged longitudinal vertical sectional view takensubstantially through the center of the chair shown in Figure 2, andwith dotted lines showing the position of the back section in a foldedposition.

Figure 4 is a perspective view of the fulcrum means used in conjunctionwith the present invention; and

Figure 5 is a fragmentary top plan view of the side members forming theseat frame.

Referring now to the drawings in detail wherein, for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral I represents the seat section of the presentinvention generally, comprising a substantially rectangular frame l2 ofsuitable material having a support board M, of an area slightly greaterthan the opening in the frame, removably secured to the upper face ofthe frame.

Secured by nails or the like to the upper face of the frame and coveringthe board I4 is a seat cover 18. Suitable padding [8' is interposedbetween the frame, the board l4 and the cover [6.

Fixedly secured to the lower faces of the side members ill of the frameI2 is a pair of spaced parallel, longitudinal runners or wedge-shapedmembers 20 that bear upon a suitable supporting structure such as a seatboard 22, to retain, the seat frame at an inclined angle with the seatboard 22.

U-shaped members 24 having one of their legs rigidly secured to a hinge25 removably carried by the opposing faces of the wedge members 20engage the forward edge of'the seat board 22, and clamp screws 26carried by the web portion of the members 24' adjustably bear againstthe under side of the seat board 22, for retaining the seat in positionthereto.

Removably secured to the upper face of the frame H2 at the rear cornersthereof is one leg of a pair of angle iron fulcrums or ears 28 having anotch 30 at their upper corners, whereby rigidity of the structure isassured and so that the reduced width leg will not project outward fromthe back rest or section which will presently be described.

The numeral 32 represents the back section of the present chairgenerally, comprising a pair of spaced parallel side members 34 havingtheir forward and rear side edges converging upwardly. The enlargedlower terminals of these side members are pivoted, as at 36, betweennotches 31 provided in the rear outer corners of side members l9 and tothe outer faces of the angle fulorums 28.

Extending between the side members 34 and suitably secured thereto, is apair of spaced parallel cross members 38 between which there is looped aback covering 40 that is secured to the rear faces of the cross members.A suitable padding 42 is interposed between the covering 40 and theopposing faces of the side members.

Also fixedly secured between the side members 34 adjacent their freeends is a carrying panel 44 which is provided with a hand-receivingopening 46. I

One end of a strap 48 is rigidly secured to th lower face of the framel2 and the free end of the strap is provided with a female snap 59 thatengages the male snap 52 carried by the rear face of the panel 44 forholding the back section in a folded position relative to the seatsection, as shown best in dotted lines in Figure 3.

It should be noted that to further support the side members 34 and tostrengthen the back sec- 3 tion, there is provided a further crossmember 54 rigidly secured between the side members adjacent their hingedends.

When not in use, the clamping members 24 may be folded inwardly to restupon the lower face of board I4. It is preferred that when in thisfolded position the lower or outer edge of the members 24 will lie inthe same plane as the side member IQ of the seat frame so that thedevice may be conveniently handled when folded without any protrusionsthereof and whereby the same may be packed into a relatively small areacase or the like facilitating transporting of the same.

In view of the foregoing description taken in conjunction with theaccompanying drawings, it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention, the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

said sections in a folded position, a pair of longitudinal wedges fixedto the seat for holding said seat at an inclined position to asupporting surface on which the same is applied, said attaching meansincluding clamps and hinges securing said clamps to said seat, saidclamps being folda- 4 ble against said seat and between said wedges.

2. A foldable chair comprising a seat section and a back section, saidseat section including a substantially rectangular frame member, a pairof angle members secured to one end of said frame member, said anglemembers having upstanding leg portions, said back section including apair of side members pivoted adjacent one of their ends to theupstanding leg portions of said angle members, upper and lower crossmembers terminally fixed to said side members, a flexible apronembracing both of said cross members, 2. padding enclosed within saidapron, a pair of longitudinal wedge members fixed to and depending fromsaid frame member and extending throughout the length of said seatsection, a pair of clamps for attaching the seat section to a supportingstructure, hinges securing said clamps to the seat section for swingingmovement of said clamps transversely between the wedge members, a seatpadding mounted on said frame member and secured to the hinges, andmeans for holding said sections in juxtaposition.

3. The combination of claim 2 wherein said clamps include U-shapedmembers having outer leg portions and adjustable pressure screws carriedby the outer leg portions of said U-shaped members.
